Answer:
Consider the heterozygous oval, thick cell walled bacteria to have the alleles OoTT and the thin cell walled bacteria to have alleles oott. Results will be 50% oval, thick walled bacteria and 50% round, thick walled bacteria. This will be the F1 progeny.
When the oval, thick walled bacteria from the F1 progeny is cross bred with round, thick walled bacteria then 25 percent of the bacteria will be heterozygous oval, thick walled. 25 percent will be heterozygous oval and heterozygous thick walled. 25 percent will be round and thick walled. 25 percent will be round and thin walled.
The correct answer is (C) biomass at each trophic level
Pyramid of energy is a graphic representation of amount of energy trapped per unit time and area in different trophic levels of a food chain with producers forming the base and top carnivores the tip. As the biomass of producers are always greater than the carnivores, the pyramid of energy can't be inverted.
I believe the part of the cell theory you can use to refute his claim is that cells are the smallest unit of life and more importantly that all cells come from other living cells.
The correct option are as follows:
estimating temperature to the nearest tenth of a degree
estimating the mass of the sample to the nearest tenth of a gram
the position of the cups of sand and water under the heat lamp
<u>Explanation:</u>
Error is an uncertainty or the amount of deviation in a physical quantity. There may arise some deviance while measuring physical quantity due to approximation.
Instrumental, environmental, procedural, and human are some of the common sources of error. The error can be classified into two types:
i) Random error
ii) Systematic error
Types of error are determined based on the deviation in the result. While observing the temperature of something, the temperature should be noted to the nearest tenth of a degree. In similar way, the mass of the sample should be estimated to the nearest tenth of a gram.
